A06901
Braking Module: Pre-alarm I2t shutdown
Drive object:
A_INF, B_INF, S_INF
Reaction:
NONE
Acknowledge:
NONE
Cause:
The Braking Module signals "Pre-alarm I2t shutdown" via terminal X21.3.
This signal is interconnected via binector input p3865[0...7].
Note:
The pre-alarm I2t shutdown is only possible for "booksize" formats. This function is not supported for "chassis" for-
mats.
Remedy:
- reduce the number of braking operations.
- check binector input BI: p3865[0...7] and the wiring from terminal X21.3 of the particular Braking Module.
A06904 (N)
Braking Module internal is inhibited
Drive object:
B_INF
Reaction:
NONE
Acknowledge:
NONE
Cause:
The internal Braking Module was inhibited via the binector input BI: p3680 = 1 signal.
In the inhibited state, energy cannot be dissipated using the braking resistor.
See also: p3680 (Braking Module internal inhibit)
Remedy:
Release the internal Braking Module (BI: p3680 = 0 signal).
Reaction upon N:
NONE
Acknowl. upon N:
NONE
A06905
Braking Module internal I2t shutdown alarm
Drive object:
B_INF
Reaction:
NONE
Acknowledge:
NONE
Cause:
The internal Braking Module outputs an alarm due to the high I2t value.
80% of the maximum switch-on duration of the braking resistor has been reached.
Note:
This message is also displayed via BO: p3685.
See also: r3685 (Digital Braking Module: Pre-alarm I2t shutdown)
Remedy:
Reduce the number of braking operations.
F06906 (A)
Braking Module internal fault
Drive object:
B_INF
Reaction:
NONE
Acknowledge:
IMMEDIATELY
Cause:
The internal Braking Module outputs a fault due to overcurrent or an excessively high I2t value and is therefore inhib-
ited.
Note:
This message is also displayed via BO: p3686.
Fault value (r0949, interpret bitwise binary):
Bit 0 = 1: I2t exceeded
Bit 1 = 1: overcurrent
See also: r3686 (Digital Braking Module Fault)
Remedy:
Reduce the number of braking operations.
Reaction upon A:
NONE
Acknowl. upon A:
NONE
F06907
Braking Module internal overtemperature
Drive object:
B_INF
Reaction:
OFF2 (NONE, OFF1)
Acknowledge:
IMMEDIATELY
Cause:
The temperature sensor connected to the braking resistor signals an overtemperature. The Braking Module is still
active. If the overtemperature continues for an additional 60s, the Braking Module is shut down (F6908).
